Troubleshooting Procedure

Possible Causes

Solution

Check whether the CBH system version is the latest.

The CBH system version is too old.

Upgrade CBH by referring to Upgrading the Version of a CBH System.

Check whether the files to be uploaded or downloaded are compressed.

In CBH, file folders must be compressed into packages for uploading and downloading.

Compress the folder into a package and upload or download the package.

Check whether the upload/download permission is obtained.

The resource file management permission is not enabled, and the user is not authorized to upload or download files.
  1. Enable permissions to manage files for a certain resource.
  2. Grant file upload and download permissions to users.

Check the cache space of the browser.

The browser cache space is insufficient.

Clear the browser cache and upload the file again.

Check whether the personal net disk has available storage space.

The Personal Netdisk works as a disk and cannot be automatically cleared. The Personal Netdisk space is insufficient, or the available disk storage space of the system is insufficient.

Check the file is too large to be uploaded or downloaded.

The file has reached the maximum size allowed.
  • Split the large file into several small files of about one GB and upload or download the small files in batches.
  • If the size of the file to be uploaded or downloaded is greater than the remaining Data Partition, contact the administrator to clear the system space or change specifications of a CBH instance.

Check whether the web login timeout period is appropriate.

Uploading or downloading large files takes a long time, and the web login connection times out. As a result, uploading or downloading large files fails.
  • During the upload or download process, check the upload or download page irregularly to avoid system timeout.
  • Ask the administrator to change the web login timeout interval.
  • Ask the administrator to set the personal net disk capacity. For details, see How Do I Set the Personal Net disk Capacity?

Check whether the protocol and upload tool used by the client are compatible with CBH.

CBH does not support file upload or download using the Debian+RDP protocol or the ZOC tool.

Use the protocols supported by CBH and the corresponding client tools to upload or download files.

  • SFTP: Xftp 6 or later, WinSCP 5.14.4 or later, and FlashFXP 5.4 or later
  • FTP: Xftp 6 or later, WinSCP 5.14.4 or later, FlashFXP 5.4 or later, and FileZilla 3.46.3 or later

Check whether the SCP command on the host is available.

SCP is not installed.

You need to install SCP on the ECS server.

File Upload or Download Failures During SSH Client O&M

Symptoms

If you use the Xshell client to log in to the hosts configured with the SSH protocol, the Xftp client cannot be called to transfer files.

Possible Causes

File transfer and transferred file auditing are disabled by the CBH system for O&M using an SSH client.

Solutions

  • Configure the FTP/SFTP protocol for the host with the same IP address and use the FTP/SFTP client to transfer files.

    For example, you can configure the SFTP for the host and assign access control permissions for the host. Then, you can directly log in to the host on the Xftp client to upload or download files.

  • Log in to the host configured with the SSH protocol using a web browser to upload and download files.

If the problem persists, click Service Tickets in the upper right corner of the management console and submit a service ticket.
